I'm going to try the suggestion to create a new VM and copy the .hdd file as noted in this article. To see if that works, if so, I'm interested to do a diff. I was too frustrated last week to give this a shot as it seemed out of the question to me at the time. @Marat@Parallels: If I still run into an issue, I will generate a problem report & upload the memory dump file. Thanks for the instructions. BTW: Thank you for posting the link to the previous version of PD11, much appreciated!
